Contact resistance and connection reliabilityContact resistance is set by a few microscopic contact spots and the films that cover them, not by the apparent contact area. This article explains constriction and film resistance, the roles of normal force, wipe and plating, how contact resistance is measured, and how it links to temperature rise and current derating. - 02

Connector selection for high-vibration environmentsVibration rarely breaks a connector outright; it degrades the contact interface through micromotion, fretting and intermittent interruptions. This guide explains the failure mechanisms, the connector and cable features that resist them, and how sinusoidal, random and shock tests are used to qualify a connection. - 03

Connector solutions for medical equipmentConnectors in medical electrical equipment form part of the means of protection that IEC 60601-1 requires, and they must survive daily cleaning, repeated mating and, in some cases, sterilisation. This note covers insulation and spacing, mis-mating prevention, chemical resistance, biocompatibility and the documentation a device maker needs from its interconnect supply chain. - 04

Reliable connectivity in automotive applicationsVehicle connectors must keep a low, stable contact resistance through years of vibration, temperature cycling and exposure to fluids, while being assembled at line speed. This note covers the environmental loads, the test philosophy behind USCAR-2 and LV 214, assurance features such as TPA and CPA, and the extra requirements of high-voltage and high-speed data connections. - 05

Understanding connector datasheetsEvery value on a connector datasheet is valid only under the conditions it was determined in. This guide explains how to read electrical, mechanical and environmental ratings, derating curves, materials, approvals and ordering codes — and which questions to ask when the datasheet does not answer them. - 06

How to select an industrial connectorA structured way to choose an industrial connector: define the electrical load, the mechanical and environmental conditions at the connector, the termination and the mating regime, then let each requirement rule out connector families. Ratings are only meaningful together with the conditions under which the datasheet states them. - 07

Cable assembly design considerationsA cable assembly is a small system: conductors, insulation, jacket, shielding, terminations, connectors and strain relief that must work together for the life of the equipment. This guide covers requirements capture, material and termination choices, testing and the documentation that makes an assembly reproducible. - 08

Shielded vs unshielded connectorsA shield only improves electromagnetic compatibility when it is continuous from cable to housing to panel, with low impedance at the frequencies that matter. This article explains how foil and braid shields work, what transfer impedance measures, why 360° termination outperforms pigtails, how to approach shield grounding, and when an unshielded connection is the better engineering choice.
